Il calabrone asiatico (vespa velutina) sta arrivando in Svizzera: scoperto per la prima volta in Francia nel 2004, è ora alle porte della Confederazione e le autorità giurassiane (cantone che per primo rischia un'invasione) si stanno preparando.
Questo predatore, che divora le api, non ha nemici naturali e rappresenta quindi un grande pericolo per le produttrici di miele presenti sul territorio.
Individuato un nido, va distrutto da un professionista
Il metodo più efficace per la sua eliminazione resta la distruzione dei nidi. L'insetto è, sì, pericoloso per l'uomo, ma non più del suo cugino europeo, già presente sul territorio.
